SPOOL Filed April 18, 1930 um/Mist L554 7. HA/VD Patented Apr. 5, 1932UNITED STATES LESLIE T. HAND, OF BROOKLYN, NEW YORK SPOOL Applicationfiled April 18,

Telegraph companies, cable companies, stockbrokers and others employingtelegraphic printing machines with which to print and transmit messages,market quotations and customers orders upon tape are accustomed topreserve the printed ta e or a carbon copy thereof for future re erence,and my present invention relates to a novel form of spool which isespecially adapted to have wound thereon a length of printed tape,whereby the spool, with the tape thereon, constitutes a record insuitable and convenient form for filing.

It is another purpose of my invention to provide means for stacking anumber of these spools closely together in a box or container, and tothis end the sides of the spools are required to be flat, without anyprojecting portions that would prevent adjacent spools from being packedtogether, without inter mediate spaces.

With these and other objects in view my improved spool consists of apair of disk-like walls, composed of flexible sheet material, and acentral spacing member which serves as a drum on which to wind the tape.

The spacer or drum has a central orifice and is counter-sunk on itsopposite sides to provide annular depressions at the perimeters of saidorifice. A ferrule or eyelet is fitted in the drum orifice and inaligned orifices in the side walls, with its ends swaged or clampedagainst the outer surfaces of the side walls, the swaged or upset edgesof the eyelet thereby pressing material of the side walls into theannular depressions of the drum, whereby the outer surfaces of the sidewalls are left devoid of any projecting portion, such as would becreated if the eyelet ends were swaged or upset upon said side wallswithout provision of said annular depressions in the drum.

Other features and advantages of my in vention will hereinafter appear.

spools, placed side by side, each spool being filled with tape.

' Fig. 4 is a detail, side view of a drum and a portion of a side wall,broken away, connected therewith.

Fig. 5 is a perspective view of a drum, and

Fig. 6 is a perspective view of a container, filled with the spools.

My improved spool consists of the disklike walls, 1, 1 each composed offlexible sheet material, such for example as pasteboard.

These walls 1, 1 are spaced apart, in parallism, by means of a centrallydisposed, intermediate drum 2, which itself is pierced with a centralorifice 3, that registers with corresponding orifices 4 in side walls 1,1.

The drum 2, at each side thereof, is provided with an annular, bevelleddepression 5 at the perimeter of orifice 3.

Placed within orifices 3, 4 is a hollow ferrule or tubular member 6,whose length is sufficient to permit its opposite ends to be swaged overupon the side walls 1, 1, about the edges 4:, 4 thereof, thereby formingmember 6 into an eyelet.

By reason of the depression 5 at the opposite sides of drum 2 theoperation of swaging member 6 enables the upset ends of said member topress the edge portions of the side walls into said depressions, andalso provides a countersunk condition in said side wall edge portionsadapted to seat the upset ends of member 6 so that the eyelet lies flushor in non-projecting relation with the outside planes of the walls 1, 1,and therefore does not present any projection outside said planes.

Thus, as shown in Fig. 3, spools placed side by side are enabled to lieclosely together.

In Fig. 6 there appears a rectangular casing 7 adapted to contain agiven number of spools, placed side by side, and snugly fitted therein.

The importance of providing eyelets that are counter-sunk to be flush orin non-projecting relation with the planes of the outer surfaces of thespool side walls will be appreciated by reference to Figs. 3 and 6especially when it is pointed out that thereby the full desired numberof spools can be packed in the container without the interference thatwould occur from projecting eyelet portions, this condition, renderedpossible by my invention, also permitting single spools to be easilyremoved from and inserted 5 in a container occupied by other spools.

It is necessary that the spool walls should be composed of flexiblematerial because when affixing an end of the tape 8 to the drum thewalls must be spread apart while the user is 10 performing thisoperation.

The spools, when filled with printed tape; are stored in the container,for future refer.-

ence.

Variations within thespirit and scope of my invention are equallycomprehended by the foregoing disclosure.

I claim:

The improved spool which consists of parallel side walls composed offlexible material, a spacing drum therefor, said walls and drum havingaligned orifices, said drum provided on both sides with annular,conoidal depressions about its orifice, and a tubular member fittedwithin said: orifices with its ends upset to press the edgeportions ofthe flexible side walls into said depressions, and having its upsetportions lying within said depressions in non-projecting relation withthe outside planes of said side walls.
